I think
@Acrobat7 simply has a German view about all this. Part of the connection between fans and clubs here is that the professional teams are owned by the actual clubs consisting of members/fans (at least the majority of the team and yes there are a few generally disliked exceptions to this rule).
This is a far different and arguably stronger bond than what you have in England where the professional teams have been privately owned for a long time.
From our perspective you lack influence in your club so the only thing you can do if you don't like what the club is doing you only can walk away (or at least try to talk to the owners about it at first, but the only truly actionable thing is stop spending money on the team).
I get that this is hard if you have been a fan of such a club your whole life and don't want to give that up, so I won't judge anyone who stays a fan of Newcastle, Man City or Man United if the Sheikh had bought them.
That said I think that every fan who actively embraces this kind of ownership is a despicable human being and should be publicly shamed as a supporter of torture, slavery, terrorism etc (list to be adjusted a bit depending on the actual state behind each club).
